Scientific Name: Botia striata Narayan Rao, 1920
Common Name(s):

Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2011
Date Assessed: 2011-03-19
Assessor(s): Dahanukar, N.

Botia striata is assessed as Endangered because the species is a habitat specialist and is inferred to have an area of less than 400 km2. Further the species is known from only four fragmented locations. The habitat of the species is severely threatened because of deforestation leading to siltation, recreational activities on the mountain tops and pollution of the hill streams.

Geographic Range [top]

Range Description:Botia striata is endemic to the Western Ghats of India (Dahanukar et al. 2004). It has been recorded from Tunga and Bhadra rivers of Karnataka (Rao 1920, Shahanawaz and Venkateshwarlu 2009, Shahanawaz et al. 2010) and Panchaganga river and Koyna river of Maharashtra (Kalawar and Kelkar 1956, Jadhav et al. 2011). Record of this species from Vamanapuram river basin in Kerala by Johnson and Arunachalam (2009) could either be a different species or an introduced population as there are no other records from this and adjoining areas.

Population [top]


The species is relatively abundant in Koyna river (Jadhav et al. 2011). However, it is rare in Tungabhadra river (Shahanawaz and Venkateshwarlu 2009).

Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Botia striata prefers clear mountain streams (Menon 1999). It is a bottom feeder and prefers sandy and gravel bottom. The habitat of this species is getting severely altered because of recreational activities on the mountain tops, deforestation leading to siltation and pollution of the hill streams, especially in the Western Ghats of Maharashtra (Neelesh Dahanukar pers. obs.).
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: Botia striata is in aquarium trade and it is caught from the wild. In Koyna the species is also sold in the fish markets by tribal people called Katkari.

Threats [top]

Major Threat(s):

Habitat alteration is the most severe threat to the species. Deforestation leading to siltation can disturb the stream bed of gravel and pebbles, which is preferred by the fish. Recreational activities on the mountain tops and pollution of the hill streams could also be threatening as the species prefers clear water.

Conservation Actions [top]

Conservation Actions:

Currently there is no conservation measures enlisted for this species. Research is needed on the population trends, harvest trends and specific threats to the species.
